It has been reported that during the culture of human placental explants, the syncytiotrophoblast dies between 3 and 24 h and is then replaced within 48 h by a new syncytiotrophoblast layer formed by the fusion of underlying cytotrophoblasts. Most frequently the death of the syncytiotrophoblast is indicated by the uptake of nuclear stains such as p...

BackgroundCilomilast is a phosphodiesterase 4 (PDE4) inhibitor for treating inflammatory lung diseases. This agent has a narrow therapeutic index with significant adverse effects on the nervous system. This study was conducted to entrap cilomilast into PEGylated phosphatidylcholine-rich niosomes (phosphatiosomes) to improve pulmonary delivery via t...

Extracellular vesicles (EVs) are endogenous nanoparticles that play important roles in intercellular communication. Unmodified and engineered EVs can be utilized for therapeutic purposes. For instance, mesenchymal stem cell (MSC)-derived EVs have shown promise for tissue repair, while drug-loaded EVs have the potential to be used for cancer treatme...

Our data demonstrate that preeclamptic sera produce toxic/dangerous micro- and nano-placental EVs which activated endothelial cells. This effect was reversed by antihypertensives. The increased levels of HMGB1 in EVs may contribute to endothelial cell activation.

BackgroundThis study aimed to evaluate the effect of mesenchymal stem cell (MSC)-derived exosomes on an immune-induced liver injury model. MSCs show a unique function to modulate immune reaction although the molecular mechanisms are still under investigation. Exosomes are a nanoparticle containing microRNA and many ligands and are recognized as imp...

Long before the nervous system is organized into electrically active neural circuits, connectivity emerges between cells of the developing brain through extracellular signals. Extracellular vesicles that shuttle RNA, proteins, and lipids from donor cells to recipient cells are candidates for mediating connectivity in the brain. Despite the abundanc...
We propose a microfluidic system that generates nanovesicles (NVs) by slicing living cell membrane with microfabricated 500 nm-thick silicon nitride (SixNy) blades. Living cells were sliced by the blades while flowing through microchannels lined with the blades. Plasma membrane fragments sliced from the cells self-assembled into spherical NVs of ~1...
